Level Minitop Hardware
IF GLASS DOES NOT CLOSE/STAY OPEN PROPERLY- LEVEL MINI TOP HARDWARE
During shipping, it is possible that the mini top hardware housing the pistons and armature has been jostled out of
position. This affects the opening angle of the glass.
1. Be sure mini top hardware is level front to back by placing a level along the top of the mini top housing at each
hinge location. If it is not, you will need a shim kit before you can correct. Order from Hussmann
Chino.
2. Remove top glass and panel at top of hardware housing.
3. Mark position of hardware (glass) in relation to case before loosening hex screw using masking tape applied on
mini top hardware and case, and pen. Hex screw allows realignment of glass angle and position front to back.
4. Raise glass and loosen hex screw. (See item/diagram #6 on page 13.)
5. Shim to adjust until level using shims available from Hussmann Chino (16 or 20 gauge stainless steel).
6. Check angle by using level placed on top of mini top hardware. Note: a 6" level will fit perfectly within access area.
7. Remove 1 1 / " chrome cap at front of case arm support. The removal of this cap allows finger access to hold nut
4
plate while tightening hex screw.
8. Hold nut plate and tighten hex screw.
9. If there is still a problem with glass staying open over-level by adding an addition shim under front of case.
NOTE: BEFORE MAKING ANY OF THE RECOMMENDED ADJUSTMENTS, VERIFY THAT THE CASE(S) HAVE
BEEN LEVELED PROPERLY.TIPS & TROUBLESHOOTING

Then see Item 4 / Uneven Gap.
B. If pinched at the bottom:
Gap is more narrow at the bottom
than at the top.
